The RS4 is Audi’s highest performing vehicle in its A4 range. Most were bummed that the introduction of the B8 variant only came in Avant instead of both the Avant and saloon form. But nonetheless as with most RS version, they never disappoint. In these spy shots one can notice it has wider wheel cases at the front and back which denotes the car has a wider track suitable for the range-topping RS4 derivative. This is pretty much an RS4 dressed as an S4.
As for power, who knows how much it will produce since most sportscar derivatives are downsizing like the BMW F80 M3 and W205 Mercedes-Benz C63 AMG meaning that the RS4 might receive a highly tuned version of Audi’s 3.0 L supercharged V6 found in the S4.
